PEGGlNG-JACK.

SPECIFICATION forming part of Letters Patent No. 461,328, dated October13, 1891.

Application filed January 23, 1891.

To all whom it may concern:

Be it known that I, GEORGE DORWART, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and ImprovedShoe-Jack, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement in that'class of jacks which areused for holding boots or shoes in position, so that the variousoperations of making may be conveniently performed on them; and theobjects of my invention are to producea jack on which the shoes or bootsmay be quickly and easily fastened and which may be easily brought intoa position for the shoes to be conveniently operated upon, and also toproduce a toepiece which will enable the shoes to be clamped firmly inposition without injuring them, and which will also adjust'itself to thevarious movements of the shoes while they are being operated on, andwill thus prevent the shoe-uppers from being scraped or otherwiseinjured.

To this end my invention consists in certain features of constructionand eombina-' tions of parts, which will be hereinafter de-.

scribed and claimed.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the jack embodying my invention, theposition of a shoe thereon being indicated by dotted lines. Fig. 2 is aplan View of the jack. Fig. 2 is a broken detail view showing thebifurcated lower end of a toe-piece which is adapted to rest upon thejack. Fig. 3 is a detail View of a form of toe-piece adapted to be usedin an old-style jack, but which is provided with a roll forming a partof my invention. Fig. 4 is a detail view of another form of toe-piecewhich is also provided with niyimproved roll. Fig. 5 is a sideelevation, partly in section, of the jack provided with a sectionaltoe-rest and an extensible toe-piece. Fig. 6 is a detail front elevationof the extensible toe-piece. Fig. '7 is avertical section of the same onthe line 7 7' of Fig. 6. Fig.8 is a detail front elevation of a sleeveusedto change the height Serial Ila-378,748. (No model.)

of the heel-post; and Fig. 9 is a detail view partly in section, of afrog adapted for use in the jack.

The 'jack is provided with a flat base A, which is nearly circular inshape and which is adapted to be screwed to the top of a post or to abench, and the plate is cut away through its central p0rtion,the cutextending nearly to the rear thereof, and projecting from the plate infront of the. slot therein is a boss at, in which is mounted aspring-pressed pin B, which normally extends rearward from theboss.

A plate 0 is shaped to fitthe cutaway portion of the base A, the platebeing of substanti ally the same thickness as the base, and the plateand base are hinged together at the rear of the base, as shown at C, sothat the plate may swing vertically from the base. The plate 0 has acircular opening 0 in the central part-thereof, and an annular recessextends around the under side of the opening, forming around the upperside thereof an annular shoulder 0'. The plate has also at its front endaprojecting lip 0 over which the spring-pressed pin B extends to lockthe plate in place; but the under side of the lip c is rounded slightly,as best shown Fig. 5, so that when the. plate is dropped it will crowdthe spring-pressed pin forward, thus allowing the plate to assume itsnormal position within the cut-away portion of the base.

'Pivoted on the top of the base A and plate 0 is a frame D, whichextends longitudinally across the base, the frame having on its upperside the vertical flanges D, which are parallel at the ends, but whichare curved outwardly-at the center, as best shown in Figs. 2 and 5, thusstrengthening the flanges. The frame has also at each end a dependingflange d, which rests upon the base- A, thus serving as a guide for theframe, and also strengthening the same. The frame is cut away betweenthe flanges d and the central part thereof, so as to lighten the frame,and in one end of the frame is an opening d through the bottom to allowof the tilting movement of the heel-post. The frame D has a centraltrunnion D which extends downward through the opening in the center ofthe plate 0, and around the lower end of the trunnion is anannularflange d which extends beneath the shoulder c of the plate 0, thuspreventing the removal of the frame from the plate. The frameD is'alsoprovided on its under side with an eccentric D between which and thetrunnion is an annular recess d to receive'the central shoulder of i theplate 0, and thus guide the frame, and the eccentric D is thickest onthe opposite sides, which align with the frame D, so that when the frameD is brought into alignment with the plate 0 the eccentric D will crowdthe pin B forwardfrom above the lip 0 so that the plate and the framethereon may be swung vertically; but as soon as the frame D is swung outof alignment with the plate O the pin B is pressed into its normalposition, thus locking the plate to the base.

The heel-post E extends vertically from be-v tween the flanges D nearone end of the frame D, the heel-post E being pivoted at the lower endnear the back portion on a pin F, and theheel-post has at the top aprojecting pin 6, which is adapted to enter the hole in a shoe-last. Theheel-post E has also at its lower end an elongated toe e, which restsupon the bottom of the frame D and which prevents the post from beingtipped forward. The post has also near its upper portion a projectingear Z into which ishooked a spiral spring G, the lower end of the springbeing hooked to an ear d on the bottom of the frame D, so that when theheel-post is tipped rearwardly in order to bring the toe of theshoe-last and the shoe thereon upon the toepiece the pressure of thespring will bring the heel-post back into its normal position and Holdthe shoe'firmly against the toe-piece. This feature of a spring-pressedheel-post is common to shoe-jacks, and I do. not claim it as a part ofmy invention. I

A toe-rest H has a depending shank H, as indicated by dotted lines inFig. 1, which is adapted to fit between the flanges D on the end of theframe D opposite the heel-post, and the toe-rest has also depending lugsh, which fit into corresponding recesses d in the flanges D to preventthe sliding of the toerest. The toe-rest is further secured between theflanges by means of a pin J, which extends through the flanges andthrough the shank of the toe-rest. On the upper side of the toe-rest His a series of steps H placed one above the otherand provided on thesides with vertical ribs or flanges h. The toepiece K is adapted to restupon the steps, and it has its lower end bifurcated, as best shown inFig. 2 so that the opposite arms at its lower end will slide between theflanges h of the toe-rest. The toe-piece K has also at its upper end aroll K, which is pivoted therein and which is hollowed out in thecenter, so as to fit the top of a shoe-last. The roll K is made ofrubber or of equivalent material, so that it will yield to the pressureof the shoe, and its yielding, together with its rolling, movement willprevent it from injuring the -to fit in an old-style jack, the only newfeature in the toe-piece being the rubber roll K, which is pivoted inits upper end and which I claim asa part of myinvention. The toe-piece76 (shown in Fig. 4) is also adapted to fit another style of jack and islikewise provided with the roll K at the top. I do not confine myself toany precise form of toepiece, as they may be made to fit any kind ofjack, and the roll in the top may be fitted to the various styles oftoe-pieces.

In Fig. 5 I have shown means for making the jack either a high or a lowone. The heel-post E, which is normally low, is provided with alooselast-pin e at the top, on which fits loosely a sleeve L, which isprovided with a set-screw Z, by means of which the pin maybe held at adesired height, and by placing this sleeve upon the postit makes a tallpost of it. If desired,the sleeve may be provided with a loose pin andmaybe slipped on over the ordinary rigid pin of the heel-post. In thisfigure is shown, also, a toe-rest H which is shaped like the toe-rest-H, described above, having the same steps and vertical flanges; butinstead of being formed in a single piece it is made up in sections Hwhich are shaped to fit one upon another and are held together by pins hwhich extend from one piece into holes in another, and by spring-'pressed pins M, which extend through diagonally'from a lower piece intoa correspond-- ing hole in the piece above. The springpressed pins lockthe several pieces together and extend from the front side of the jack,the lower ends of the pins terminating in suitable handles m, whichfacilitate the partial removal of the pins. sections H rests between theflanges D of the frame D, and the height of the toe-rest may be changedby varying the number of the sections. To remove a section,the pin M,which holds it, is pulled downward till it is released from the uppersection, when the section maybe easily removed.

In connection with the sleeve L an adjustable toe-piece N is used,although .it may be used with the low post and with either form oftoe-rest. The toe-piece N has lugs Non opposite sides at the top, whichcarry a rubber roll K, like that already described, and the lower partof the toe-rest is bifurcated, so that it will fit the toe-rest. At theupper end of the bifurcated part of the toe-piece are projecting lugs n,between which is pivoted a block n, which will naturally drop of its ownweight, so as to hang vertically in the bifurcation of the toe-piece,but which may be held upward by a springcatch M, which The lowest of theis secured to the toe-piece and is adapted to spring over the free endof the block. It will be seen, then, that the toe-piece may be used inconnection with either a low or a high heel-post, and by having thetoe-piece and toe-rest both adjustable vertically the jack may bequickly and nicely fitted to shoes of various sizes.

In Fig. 9 I have shown a frog P-such as is usually screwed to abench-and the frog is shaped in the main like a common frog; but itslower end P is shaped to fit in one of the sections H of the toe-restand is provided with a hole 19 to receive the pin M 'andholes p toreceive the pins 71 The frog can therefore be easily secured in thejack, and it can be used more conveniently in this way than when securedto a bench.

A shoe and last are secured upon the jack in the ordinary way, as shownin Fig. 1, and when the jack is to be tilted so as to bring the shoeinto a position to work upon its edge the frame D is swung so that itwill align with the plate 0, thus crowding the pin B from ofi thefrontlip of the plate, as described, and the jack may then be easily tilted.

Having thus fully described my invention, I claim as new, and desire tosecure by Letters Patent 1. A jack comprising a flat base having itscentral portion cut away, as shown, a plate hinged to the base so as tofit within the cutaway portion thereof, a spring-pressed pin secured tothe base and adapted to overlap the plate, a frame centrally pivoted tothe plate and provided with Vertical flanges and with an eccentric toengage the spring-pressed pin, and a suitable heel-post and toe-restsecured between the flanges of the frame, substantially as described.

2. The combination, with a base having its central portion cut away, ofa plate hinged to the base and fitting in the cut-away portion thereof,a frame pivoted to the plate and provided with a heel-post and toe-rest,and means for locking the plate in position, substantially as described.

3. The combinatiomwith the base having its central portion cut away, asshown, the plate hinged in the cut-away portion of the base and providedwith a projecting rounded lip, and the spring-pressed pin mounted on thetoe-rest and a toe-piece adjustably carried thereby, of a concave rubberroller pivoted 1n the upper end of the toe-piece, substantially asherein shown and described.

6. The combination, with a jack of the character described, of atoe-rest formed with a series of steps and made up in sections fittingone upon another, substantially as described.

7. In a shoe-jack, the combination, with a heel-post having a socket inits upper end, of a pin removably secured in the socket of the post, asleeve fitting loosely on the pin, and a set-screw for securing: thesleeve to the pin, substantially as and-for the purpose'set forth.

8. In a shoe-jack, the combination, with an extensible heel -post, of anadjustable toepiece carrying a yielding roller in its upper end,substantially as described. 7

9. In a jack, the combination, with a toerest, of a toe-piece shaped tofit upon the toerest, said toe-piece having a hinged block adapted toswing between it and the toe-rest, substantially as described.

10. In a jack of the character described, the

extensible toe-piece having a block hinged thereon and adapted to swingbeneath its seat, and a spring-catch to hold the block in an elevatedposition, substantially as described.

11. In a shoe-jack, the combination, with a toe-rest, of the frog P,adapted to fit in the toe-rest and provided with the holes 13 and p,substantially as described.
